The answer is 8% :)
Hope this helps
It would be the last answer, you can't simplify
Answer:
The expected frequency for each category would be:
10.
Step-by-step explanation:
a) Data and Calculations:
Number of respondents = 30
Number of categories = 3
Political preferences (categories) = 3
Probability of each category or preference occurring = 1/3
Expected frequency for each category = 1/3 * 30 = 10
b) The expected frequency for each political category (political affiliation) can be calculated by multiplying the probability of each category (political preferences) by the number of respondents. Note that the expected frequency will be different from the observed frequency, which is the actual number of times that each category of political affiliations will be preferred.

Step-by-step explanation:
Answer:
x = 5.2
Step-by-step explanation:
Measure of interior angle of a regular polygon = 
Here n = number of sides of the polygon
Interior angle of a regular pentagon = 
= 108°
By applying cosine rule in ΔABK,
(BK)² = (AK)² + (AB)² - 2(AK)(AB)cos(108)°
(x + 3)² = 4² + 6² - 2(4)(6)cos(108)°
x² + 6x + 9 = 16 + 36 - (-14.83)
x² + 6x = 57.83
x² + 6x - 57.83 = 0
x = 
x = 
x ≈ -11.2, 5.2
Since, x can't be negative,
x = 5.2 will be the answer.
